POWER GENERATING ELEMENT FOR LIQUID FUEL CELL, MANUFACTURING METHOD THEREOF, AND LIQUID FUEL CELL USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a liquid fuel cell having high output density and capable of sufficiently showing catalyst ability by optimizing narrow hole structure inside a catalyst layer.

SOLUTION: The liquid fuel cell is provided with a positive electrode 8 for reducing oxygen, a negative electrode 9 for oxidizing a fuel, a solid electrolyte 10 arranged between the positive electrode 8 and the negative electrode 9, and a liquid fuel 4. The positive electrode 8 and the negative electrode 9 respectively contains catalyst layers 8b and 9b each having a thickness of 20 μm or more. At least one of the catalyst layers 8b and 9b has fine pores having a diameter of 0.3 μm-2.0 μm so that the volume of the fine pores is 4% or more relative to the total volume of the fine pores.
